I am told by a source close to Dick Van Dyke that the problem really is an Achilles injury. That's good to hear…not that he's injured but that it isn't something more serious. Mr. Van Dyke will be 85 on Monday.
He has an autobiography that is allegedly supposed to come out around next April. One hopes he will be in good enough shape to make the rounds, selling and signing copies.
Anyway, moral of the story: Don't trip over footstools. It catches up with you later in life. And while you're at it, it might be a good idea to never do The Twizzle.
